2011-12-28  Fabien Chene  <fabien@gcc.gnu.org>

	PR c++/23211
	* name-lookup.c (do_class_using_decl): Use dependent_scope_p
	instead of dependent_type_p, to check that a non-dependent
	nested-name-specifier of a class-scope using declaration refers to
	a base, even if the current scope is dependent.
	* parser.c (cp_parser_using_declaration): Set
	USING_DECL_TYPENAME_P to 1 if the DECL is not null. Re-indent a
	'else' close to the prior modification.
